I've just upgraded from Elements 5.0 to CS4 (with RAW 5.0) and can only open Nikon D80 RAW files. I can't open Lumix LX3 RAW files. I tried to download the latest Camera RAW 5.3 by clicking in the Help Menu and choosing "Update". I get the message "the Installation process as encountered a problem". I then have a choice of choosing; "run update again", "stop installation", or "cancel". I'm also getting this error message with "Adobe Extension Manager CS4 2.1" update. I can't work out if there's a problem with the "Extension Manager", the RAW update, or the "Installation Manager" - if that's what it's called.

I looked in C:\program files\common files\Adobe\Plug-Ins\CS4\File Formats, and can see "Camera RAW.8bi. I'm sure that is the same name as the RAW Plug-In in Elements 5. Am I having this problem because Elements 5 is on the same Drive, or is there a problem with CS4? To add insult to inury, I have encountered a few other problems, listed below:-

I can't delete a layer by dragging it to the Bin. I have to right click on it and choose "delete layer"

When I make a Levels Adjustment Layer, there is no "OK" button to click on, to make the dialogue box disappear. That wouldn't matter too much, but I don't know how to "cancel" an amendment as I used to do, by pressing Alt key and clicking on "Cancel" to restore the changes. How do I do this in CS4?

I'd prefer all the Windows to Float, so I can move them around. I can't see how to make this a preference. I have to click on the "Window" menu and make the changes for every document. Otherwise, the picture fills the whole screen.

I made some brushes in Elements 5 - mainly a signature brush. How would Iike to copy this brush to CS4? I can see a "Brush Presets" folder, but not individual brushes in either package.

Lastly, I'd like to load CS4 on my laptop, if that's allowed. I don't often connect to the Internet with my laptop for security reasons. Do I need to be connected to load it onto the Laptop.

I bought CS4 from Adobe, and was hoping there wouldn't be a problem with the software. Upgrading from Elements 5 has been a cultural shock, so I hope I don't sound too "dim". I've watched lots of DVDs about CS3 and CS4, but still feel quite swamped with the new features.

It makes replying very difficult when you add five unrelated questions to your original one!

The camera raw problem with the automatic updater is known. It is best to download the Plug-in from the Adobe site* and install it following the instruction carefully. Make sure you completely remove the old one first!

You can delete a layer by dragging it to the "little" bin at the bottom of the layers panel or by selecting the layer and clicking on the little bin or pressing Delete. Or using the method you mentioned.

To accept a change just click on the background layer, the dialog will disappear. Or you can click on the little Arrow icon botton left.

Not only are they unrelated to the original question(s), they are unrelated to this forum

I suspect that the OP may be running on a Windows Platform both because the update problems stated are similar to those I experienced on that platform and because she gave a path that normally would exist on a Win OS. I'll give the links to both of the Photoshop forums

Thanks for this information. I need to uninstall Elements 5 (after saving the brushes I made), because it's trying to open E5 for the RAWs, which obviously it can't. I just right click on a picture and choose the CS4 RAW.

There are so many new features in PS and RAW that I'll have to buy and book and a video. I've clicked the links you sent and found the information very helpful.
